A2.04 g lead weight, initially at 10.8 oc, is submerged in 7.74 g of water at 52.2 oc in an insulated container. clead = 0.128 j/goc; cwater = 4.18 j/goc. what is the final temperature of both the weight and the water at thermal equilibrium?

Explanation:

Hello, in this case, the lead is catching heat and the water losing it, that's why the heat relation ship is (D is for Δ):

Now, by stating the heat capacity definition:

Solving for the equilibrium temperature:

Which is very close to the water's temperature since the lead's both mass and head capacity are lower than those for water.
